Referring more particularly to the drawings in detail, designates avertical support such as a wall, board or plate mounted against or in awall designed to support the cabinet thus obviating the necessity ofemploying a floor stand so that Valuable floor space may be otherwiseused. Secured to the vertical support 35. in a back mounting plate 36preferably of metal having right angular or outstanding Vertical orpar-` allel side flanges 31 designed to removably support the frame ormechanism of the device. AS shown, these side flanges are provided witha plurality of bayonet slots 38 opening at the top through the edges ofthe fianges to receive outstanding pins 39 projecting from the sideplates 46 and 4I of the frame of the machine which supports themechanism as a unit. If desired, three of such pins and bayonet slotsmay be provided, the pins 39 engaging the upper and lower slots and theintermediate slotsd being engaged by clamping screws 42 engagingthreaded apertures in the plates and 4I instead of providing pins 3S toengage the slots, so as to hold the frame from vertical displacement butpermit removal thereof should occasion arise. The frame also includesupper and lower spacing and connecting or tie rods 43 and 44 havingreduced ends forming shoulders to engage the inner faces of the sideplates 46 and 4l so as to rigidly hold the same in uniform spacedrelation parallel to each other with screws anchoring the ends of therods at the outsides of the plates. The bottom edges of the plates 46and 4l are provided with apertured ears 45 near their inner and lowercorners and the cabinet or housing 46 which is shown as beingsubstantially of rectangular form and open at the back is provided witha bottom opening 4'! flanged inwardly around the bottom edge. While thecabinet may be pivoted or hinged to the mechanism or frame near thelower rear corner of the machine to enable it to swing forwardly anddownwardly to serve as a container for holding the clean towel roll,towel guide, soiled towel roll or any other articles which mightotherwise be mislaid or dicult to manipulate during the loading of the.machine. In the form shown, the bottom flanges wardly so as toconveniently receive and retain as well as render accessible any partslplaced therein. When closed, it is swung upwardly and may be held lockedby any suitable means to prevent access to the interior of the cabinet.As shown. a locking screw 49 is provided in the top wall of the cabinetadjacent the open side and edge thereof which may be operated by asocket or plug wrench or key to engage the keeper or aperture of anangle bracket 56 secured to the mounting yplate 36. If desired, a mirror5l may be provided at the front of the cabinet and held at the back by aremovable plate 52 over an opening in the front of the cabinet withsuitable interposed cushion packing to prevent breakage of the mirror.

A bottom plate 53 is provided for the cabinet but is supported betweenthe side plates 40 and 4I` of the frame and this bottom also serves as aseparator between the clean toweling roll and the ascending soiledtowelingand can be swung clear of the back of the machine or backmounting plate 36 to provide ready access thereto for simplifying thetask of loading as will be hereinafter more fully explained. The frontedge of the bottom plate 53 is shown rolled or curled up as at 54 spacedfrom the front wall or bottom edge of the front portion of the cabinetand at the back or rear corner iscurved upwardly as indicated at 55 overthe lower rod 44 to receive and support the clean towel roll when thesame becomes small. This plate is then extended vertically as at 56 toform a separator or vertical partition in spaced parallel relation tothe back mounting plate 36 and provide a narrow transverse verticalchannel 58 therebetween through which the soiled or used towel may bepassed to the winding or take-up roller, as will be later described andprevent contact thereof with the clean toweling. The top edge of thevertical plate portion 56 is provided with an angular portion 51directed forwardly and then upwardly to frictionally spring orresiliently set under and against the upper rod 44 to hold the plate inposition at the back of the frame in front of the channel or space 58.The `bottom 53 is pivoted between the side plates 40 and 4I preferablyin spaced relation to the rolled front edge 54 and for this purpose, mayhave angular brackets 59 of L-shaped form rigidly secured thereto at thetop by riveting or otherwise and provided with outwardly extending pivotlugs 59a extending through correspondingly located apertures in the sideplates 40 and 4|. In this manner, the bottom plate together with thepartition may be swung on the pivots so that the curled end 54 swingsdownwardly and rearwardly, the bottom portion 53 upwardly, and thevertical portion 56 upwardly, forwardly and downwardly so as to exposethe back of the cabinet or frame when the clean towel roll is not inposition.

thereto 'so that the short side .of theplate ex- 90 are retained inposition by strips or slides 93 mounted on the reduced ends of theflanged collars 9| and held by clamping screws 94. The slides 93 haveoutstanding angular or bent ends 95 to each of which a coiled spring 96is anchored at o-ne end and at the opposite end by means of screws orthe like to the plates 40 and 4I of the frame as indicated at 91 so asto normally exert upward-tension to press the soiled towel roller Stoward the winding or take-up roller W. Each slide 93 is provided with aiinger piece 9S bent therefrom to extend between the plate and a housing99 of angular flanged construction secured to the outer faces of theplates 40 and 4I and each having .a slot |00 through which said ngerpiece operates. Lugs IUI are provided on the side plates spaced from thelower ends of the guide ways or housings 99.

The feeding and Winding or take-up rollers F and W constituting thef'riction or sand rollers are substantially alike in construction andeach comprises a tubular cylinder or tube |02 of metal or other suitablematerial and provided with aligned longitudinal slots |03 near each endthrough which the tapered ends |04 of a spirally Wound emery or sandpaper strip |05 are bent, inserted and anchored, the strip beingsuitably anchored or glued to the cylinder if desired. The ends of thecylinder are provided with spaced segmental notches |06 equidistantlyspaced apart and preferably three in number forming correspondingintermediate projections |01. Disks |08 forming webs or heads fit thenotched ends of the cylinder Aor body and for this purpose are providedwith spaced projections |09 to enter the notches |06 and correspondingnotches I I to receive the projections |01 to reinforce and close theends of the tubes as well as connect the cylinders and disks to causethem to rotate together. The disks or webs fit snugly in the ends of thecylinders and are provided with outwardly projecting tubular anges orhubs III forming spacing means between the disks and the frame members40 and 4I and receiving shouldered tubular trunnions I I2 which arekeyed to the disks |08 and the hubs I I I to turn therewith.' Thetubular trunnions I I2 are provided with two opposite flattened surfacesI I3 at their outer portions and a peripheral groove I I4 circumscribingthe same and intersecting the iiattened portions. Flanged bearings l iare mounted on the trunnions I|2 and have their flanges positionedwithin and against the inner face of the plate 4I) adjacent the hub I IIat one side of the frame. At the opposite side a separate or removablebearing plate I |6 is bolted to the plate 4| and has a sleeve or hub II1 extending into an opening |I8 of larger diameter than the hub I I Ias seen in Fig. 3l. Screws I9 secure the plate I I6 in position and atie rod |20 extends through the roller and the tubular trunnions orbearings I I2 and have their threaded ends anchored as by nuts |2Iengaging threaded ends of the tie rod thus to hold the parts inassembled relation and against end thrust by engagement with the ends ofthe tubular trunnions or bearings I I2. At one side of the frame,sprockets |22 are mounted on the flattened portions I|3 of the trunnionsand fixed by a set screw |23 while an endless drive member or chain |24is trained around the sprocket wheels to cause the friction rollers torotate in unison. They are held in position by spring cotter pins |25which engage the annular grooves II4 at one end, preferably the rightside of the machine although this is optional. The corresponding endofthe winding roller W is provided with a ratchet wheel |26 on theflattened portion I I3 of the trunnion I I2 with its hub or collarbetween the plate |I6 and the hub or collar of the sprocket wheel |22(see Fig. 5). At the bottom roll F, there is no ratchet wheel but thecollar is retained (see Fig. 31). The teeth |21 of the ratchet Wheel |26are engaged by anpawl |28 pivoted at |29 to a boss on` the plate 4I andheld by a spring |30 into engagement with the teeth |21 so as to preventbackward or retrograde movement of the winding roller so that the soiledtowel cannot be unwound from the soiled towel roller and so that theparts can only be driven in one direction tending vto feed the cleantoweling and wind the soiled toweling. A collar |26a is mounted to takeup space on the trunnion |I2 of roller F at the bottom, in lieu of theratchet wheel |26 as provided on the roller W at the top where theratchet wheel |26 end pawl |28 are provided to prevent reverse rotation,and to avoid end thrust. However, this construction permits quickremoval and replacing of a friction roller by simply removing the nuts|2I, rods |20 and drive parts by ref moving the screws I9 of the platesI I6 so that the hubs III at that side can be displaced through thecorresponding openings II8 and the webs or disks set in the ends of thebody |02 displaced outwardly so that the body or cylinder can beremovedand a new one inserted and secured in position. Thus, the notchedconstruction of the friction or sand rolls where the 'disks or webs setinto the ends of the body or cylinder of the roll enables replacement ofthe worn friction or sand surface by substitution of the body only byreason der and its sprocket Wheel to turn together because the nuts I2|are jammed against the bearing sleeves o-r trunnions I I2 at thethreads. Thus, the hubs I I I will also be slightly loose on thetrunrnions I2 but not broken and the machine will not be out of service.The cost of this common type repair is reduced to just a fraction of theusual cost or entirely eliminated by this construction.

The control mechanism of the machine for the feeding, winding, timingand time release mechanism is preferably mounted at the left hand end ofthe lower friction or feeding roller adjacent the plate 40 at theoutside and for this purpose a spur gear or pinion I3I vis mounted onthe flattened portions I I3 of the trunnion I|2 and is held in positionby a spring cotter pin |32 engaging the annular groove |I4 adjacent theflanged bearing |I5 at that side. The gear |3| also held by keys |33tting the flattened portions ||3 and registering recesses in the gear asshown in Figs. 6 and 31. A gear |34 meshes with the gear |3| and its hubextension |35 carries a smaller gear or pinion |36 on the outside. Atthe inside, the hub |35 is provided with a squared portion |31 havingfour flat surfaces the inner portions of the corners of which arerounded as at |38 (see Figs. 25 and 26) forming corner shoulders |39facing inwardly. A sleeve |40 ts Within the hub |35 and forms a bearingfor the gears |34 and |36. This sleeve isrmountedfon.

The soiled toweling rol-ler S ismerely` displaced. fromL the open bearings or recesses 66 intheupperends of the bearings 90. A length of clean toweling T is then unrolleclfrom the clean towel roll C and with the plate 53 swung on its pivot soas to dispose the partition or separator 56 forwardly and downwardlyrelative to its normal vertical position where it forms the space 58 inconnection with the back mounting plate the end of the toweling is thenpassed under the bottom of the machine in back of the rods 44 throughthe space 58 which has been opened by the forward tilting of the plateportion 56 so as to render accessible the back of the machine tofacilitate loading. The fact that the bottom of the cabinet is integralwith the separator which is normally positioned between the cleantoweling roll and the ascendingsoiled toweling and can be swung lclearof the back of the machine to provide ready access thereto greatlysimplifies the task of loadingi The toweling is then extended under orover the winding or take-up roller W and the endv portion thereof woundupon the soiled towel roller S which is placed in position in the`bearings 90 and pressed against the roller W by the tension of thesprings 96. The plate 53 is then swung back into position with itsvertical portion or partition 56 in front of the ascending towelingwhere it is held by the angular portion frictionally and resilientlykengaging the upper rod 44. With sufficient length of the clean towel`depending below the machine in the form of a loop. as shown in Figs. land 2, the length of which may be varied as desired, the clean roll oftoweling C is then thrust or placed in position as shown in Fig. "Iresting upon the idle roller I and the partition or separator 56 spacedabove the bottom portion 53. The separating plate 83 which automaticallyfloats with the pivoted arms 85 may be raised to facilitate insertion ofthe clean towel roll and will move down as the clean toweling isdispensed therefrom but normally `may assume the position shown in Fig.7 but always keep the soiled toweling out of contact with the cleantoweling continuously during the time when the latter is unwound fromthe roll C and being wound on the lroller S. The pinch roller and guideassembly or frame 6U is then inserted in position by engaging thenotches 55 with the pivots 66 and swinging the same rearwardly anddownwardly on said pivots so that the pinch roller P will pass or snapby the periphery of the clean toweling roll C and the idle roller Ipermitted by the slots in which the pinch roller P is journaled and thenormal tendency of the springs 13 to hold the pinch roller at the innerends of the slots. The placing of the clean toweling roll C in positionas previously explained will cause the toweling T to pass over thefeeding roller F and the idle roller I so that when the pinch rollerassembly is placed in position as just described, the pinch roller willloop or press the toweling downwardly by pressure thereon between theidle roller I and the feeding roller F and will place the pinch rollerand toweling under tension by the springs 'I3 due to the inclination ofthe slots 'Il and the tangential relation or convergence thereof towardthe periphery of the feeding roller F andl the tendency of the springsto press or hold the pinch roller against the feeding roller F andtoweling thereon below its axis |26 and at the same time the guard plateor guide 63 will be positioned over the feeding roller and the assemblyor frame held in position by engagement of the notches 68 with the pinsor lugs 59. The pinch roll is contained in an assembly which serves 3Sa, WWF-1- ing guide and is separable from the rest of the mechanismthereby positioning the pinch roller after the toweling has been thrownor placed in position. This makes threading of the toweling unnecessary.Also, owing to the fact that the pinch roller is positioned under springtension, no towel slippage is required to set the pinch roller firmlyand in position pressing against the feeding roller with the interposedtoweling. Most, if not all other machines, require motion of thetoweling to accomplish this function. The machine is now ready tooperate and when a clean wiping section of toweling is desired, the usermerely grasps the clean toweling depending bel-ow the machine at theopen bottom below the feeding roller F and adjacent the curled portion54 and a downward pull exerted thereon. Due

to the frictional engagement of the toweling with the feeding roller F,the latter will be rotated as well as the pinch roller. P and the idleroller I to unwind the toweling from the clean towel roll C. Due to thefeeding and winding rollers being positively connected by the chain |24on the sprocket wheels |22, the winding or take-up roller W will berotated in the same direction as the feeding roller F thereby advancingthe soiled toweling around the winding roller and causing it to be woundon the soiled towel roller S by reason of the latter and the towelingthereon being pressed against the winding roller W by the springs 96which elevate the bearings 96 in the slots 9-2. By holding the soiledtoweling roll in contact with the take-up or winding rolier by springtension instead of depending upon gravity as in most, if not all othermachinesY this produces a more uniformly and tightly w-ound roll ofsoiled toweling, thus reducing the space requirement of the roll. Thefloating separator or plate 83 which `can assume any position requiredby the changing sizes and positions of the toweling rolls is used toeffect a conservation of space by using the space given up by thediminishing clean roll to accommodate the increasing size of the soiledtowel roll.

In order to regulate the feeding or advancing of the toweling as well asthe Winding and the time interval of the perceptible or discerniblesignal which, as previously explained, is audible in this instance dueto the buzzing sound of the operation of the gears of the timing orclock mechanism |1| and thus indicate to the user when the device isinoperative or when the toweling may not be pulled out, as well as givean audible, discernible or perceptible signal continuously during theperiod when theJ towel is normally used for the wiping operation or theperiod while fed between the time when the towel is pulled or moved outand the time when it may be moved again, the following operation takesplace. When the toweling is pulled to rotate the feeding roller F andthe winding roller W, the latter will be permitted to rotate by the pawl|28 riding ovei` the teeth of the ratchet wheel |26 but restraining thesame against reverse rotation so that the toweling cannot be unwoundfrom the soiled towel roller. This also turns the ,gear I3| which inturn drives the gears |34, |36 and 55 thus rotating the cam or eccentric|5| and the cam |57 rigid with ygear until one of the shoulders engagesthe roller |49 to swing the arm |46 rearwardly and cause the roller |43to engage the fork of the arm |11 against the action of the spring ormotor |18. During this time, the locking pawl |66 rides on the surfaceof the eccentric I5| being so held by the spring |68.

The cam being fixed to the squaredportion |31 will be driven by the gears and the arm |46 is turned by thecam |51 engaging the roller |49 atA the shoulder |60 and at the limit ofthe movements of the arms |46 and |11 as shown in Fig. 19, they willremain in the same position during the continued rotation of` the cam|51 until the high portion |58 passes the roller |49 and the latter onthe action of the spring |18 is free to move down the shoulder |6| intothe low portion |59 to permit the clock mechanism or timing gear |1| tooperate for an exact period determined by the angular adjustment of thebase plate |45 at the extension |44 on the pivot post |4| and the timinggear therewith through the medium of the slot |19 and held by the setscrew |80. The further the base plate |45 is set to the left the shorterwill be the time interval during which the locking dog |66 is engagedand the toweling held locked against being pulled out and conversely,when the plate |45 is set to the right, said time interval will belengthv ened or increased accordingly. This is due to the fact that theangular position of the forked arm |11 will be changed so that the openend of the slot, recess or verge thereof will face more quickly or moreslowly in a releasing direction as to the roller |48 `and as soon as thelatter as released under tension of the spring |18 it will strike thearm |61 and disengage the dog |66 from the shloulder |53 by the impactand. thus permit free movement of the toweling and the feed roller F aswell as the simultaneous rewinding or take up of the soiled towelingupon the soiled towel roller S'by the spring pressure engagement of thelatter with the simultaneously driven winding rollerW by the driveconnected between the feeding and winding rollers.v reverse rotationwill be positively prevented by the ratchet mechanism on the windingroller consisting of the ratchet wheel |26 and the pawl |28 engaging theteeth |21 thereof so that the device may not be put out of order byreverse or retrograde movement of the toweling. Fig. shows the positionof the parts after the toweling has been completely pulled out apredetermined length and the feeding roller F has turned approximatelyone and one-quarter revolutions or for a complete cycle of operationwith the roller |49 in position to be released from the high portion |58of the cam |51 down the shoulder |6| and into the low portion |59 sothat the timing or clock mechanism |1| or the gearing composing the samewill start to operate and will continuously indicate to the user by aperceptible or discernible signal which in this instance is audible andmay be produced in any suitable way, but as shown is the sound ofoperation of the clock mechanism, the time duration during which thetoweling may not be pullded out thereby to obviate pulling on the sameand possibly putting the mechanism out of order. These signals will beintermittent or alternate between each pulling of a length of towelingand the next pulling so as to indicate when the toweling is lockedagainst movement and may not be moved or pulled, as

However, thev |5| turned one-half of a revolution. The turning of` wellas when it is released and may be moved again. During this timeinterval, the cam |51 as Well as the feed roller F and the cam oreccentric |5| will remain stationary while the arm |46 which is free toturn independently thereof on the rounded portion |38 moves with theforked arm |11 of the timing mechanism |1| and remain stationary untilthe toweling is again pulled out to reset the locking mechanism and thetiming mechanism to permit the latter to operate and release the lockingmechanism after the desired time interval. By reason of the novel ratioof feeding, winding, timing and time release mechanism, as described,whereby the friction feeding and winding rollers are advanced other thanin integral number of revolutions each time a length of toweling ispulled down or out for use and arranging the toweling so as to cause thestrip of toweling to extend around or engage with the friction surfaceson'said rollers at the major or practicable maximum portions of theirperipheries, but more particularly to cause the engagement of the pinchroller P with the roller F as Well as the soiled towel roller S with thewinding or take-up roller W at a different point on the periphery of thefeeding and winding rollers respectively when stopped after each cycleof operation or moving of the toweling to advance a clean section towiping position thereby preventing undue wear on the friction surfaceson said rollers at any particular point as where one point on the rollerF stops in ccmfronting position to the pinch roller P or one point onthe winding roller W stops in confronting position to thefsoiled towelroller S at each operation, increase in the useful life of the rollersurfaces is insured. In the particular arrangement shown, a differentsurface will be presented to the pinch roller for every multiple of fouroperations before repeating and before the same point is again contactedthereby preventing undue wear on the friction surfaces, emery paper orsand paper of the friction or sand rollers constituted by the feedingand winding rollers and increasing the useful life of said rollersurfaces a multiple of or approximately four times their ordinary life.The construction of the means for supporting and feeding the cleantoweling as well as winding up the soiled toweling, the arrangement ofthe rollers and the manner in which the toweling is run through themachine as well as the construction of the rollers for feeding andwinding up the toweling and the arrangement of the pinch roller P and.the soiled towel roller S held under constant spring pressure againstthe respective feeding and winding rollers F and W respectively insuresuniform, even and positive feeding and winding of the toweling as itmoves down at the front and up at the back. This is also due to the factthat the soiled toweling roll is held in contact with the take-up orwinding roll by spring tension instead of depending upon gravity as inmost, if not all other Imachines, thus not only producing a moreuniformly and tightly wound roll of soiled toweling but also reducingthe space requirement of the roll. The pinch roll is also contained inan assembly or frame which serves as a toweling guide by reason of theopposite edges of the toweling strip feeding between the end plates 6|thereof and between the feeding roll and the guide plate 63 which isdisposed in spaced concentric or parallel relation thereto. By havingthe pinch roll assembly separable from the rest of the mechanism, thepinch roll may be placed in posivgiven up by the diminishing increasingsize of the soiled towel erroneos .tionr after toweling ihasbeenimountedrinipnsit'mn, tthus `making `threading zof the toweling ibe- Athetoweling is :also facilitated fespecial'ly due-'tto pressing` againstthe feeding roll under spring.` tension and positioned or lsnapped inposition' duek to fthe :feeding `sind winding frollers :being fof thefsame diameter, -foperatively :connected as described :andidirectly:controlling fthe feeding and winding thereof, as vwell ;as theregulating and timing mechanism and.intervals -when lthe fdeviceis;locked in addition '.to. the means .for preventing retrogrademovement:or iunwinding-.of 'the soiled under such tension over the feedingroller and l under the clean towel roll so that the toweling is loopeddown between, the idle roller I and the feeding roller F by the pinchroller P when in position as more particularly shown in Fig. 7 of thedrawings, no towel slippage is required to set the pinch roller firmly.The toweling is maintained in constant uniform contact under pres- 1sure with a maximum surface or more than half the circumference of thefeedingroller F as well as in engagement with the idling roller. This yis also due to the engagement of the toweling' I with the winding rollerW over .more than onehalf the circumference thereof and is furtherinsured by the pressure between the toweling on the soiled towel rollerS and the periphery ofthe winding roller W due to the resilient'mountingf of the soiled towel roller and the action of the springs 96v inmaintaining the roller S and the soiled toweling wound thereon againstthe surface of the roller W by means of the spring held bearings 90. Theseparators SG1-and 83 also maintain the clean toweling out of contactwith the soiled toweling and .the latter separator compensates for thevarying sizes of the clean and soiled toweling rolls. 'By reason of theoating action thereof so that the separator 83` can as` sume anyposition required by the changing sizes and positions of the towelingrolls, a conservation of space is effected by utilizing the space cleanroll to accommodate the roll and when the clean towel roll issufficiently small it may drop between the idle roller I and theverticalv plate 56 on to the bottom 53 while still pressing against theidle roller I and increasing the surface contact withthe latteruntilentirely unwound and paid out. At vthis time the bearings 80 may bedepressed and the soiled towel roll displaced and removed by disengagingthe trunnions 88 from the bearings 90 at the open recesses 89, when themachine is again in condition for reloading in the manner previouslydescribed. The spring |18 constituting an actuating means for the timingmechanism |1| not only actuates said mechanism but upon'release of itsoperative connection with the timing mechl anism or being operativelydisconnected therefromby disengagement ofthe roller |48 from the forkedarm |11 acts to move thearm |46 and roller |48 to overcome the action ofthe spring |66 which otherwise normally holds the locking dog or pawl|66 engaged with the shoulder |53 of the cam or eccentric |5I, bycausing said roller to forcibly strike or impact the arm |61 and rej llease the pawl |66ffrom its 1ocking position holding or restraining thefeeding of the clean toweling. ',The cam |5| will ride against and holdthe pawl |66 out until again engaged by the shoulder -or stop |53-whilethe cam |5| is turned by pulling out and feeding the toweling T: Itshould also be noted and will be apparent from the foregoing descriptionof the construction and operation thaty l towelingfroll, ithe soiledgtoweling will he :rol-led rintoztheicabifnetinthe-form of a rol-ler at:a linear rate exactly equal to the linear rate at which the cleantoweling is uniformly dispensed or pulled out according to theadjustment for which the machine is set but preferably approximatelyeight inches, thus keeping the amount or length of the depending looplof exposed toweling substantially constant. It will also appear .thatwhile the length of toweling dispensed at each use is preferably eightinches, thismay be adjusted or varied as desired, as by varying thesizes of the feeding and winding rollers and the gear ratio of thedriving means or gearing train, so that each successive length oftoweling dispensed shall be and remain uniform once an adjustment ismade. Also, the operating parts, device or feed roller and the towelingare locked against movement after each pulling of the towel and thetoweling prevented from slipping when.

pulled unnaturally 'hard or in normal operation, thereby preventingrewinding of the used or Asoiled toweling on the clean toweling ro11 orunwinding the used or soiled toweling from the soiled toweling roll.Also the time interval between feed-- ings may be controlled by the timecontrolled mechanism which may be adjusted as desired, say from five totwenty-two seconds or otherwise. The time controlled mechanism as wellas all the other mechanisms, are not accessible to any one usingthemachine by reason of being enclosed in the cabinet inthe mannerdescribed, thus, preventing tampering therewith and rendering the devicefool-proof.

It may also be stated that by having the damp used toweling passupwardly against the lower tie rod 44 and the separator or plate 56under angular stress at the top and bottom, the damp toweling issmoothed at instead of leaving the same folded, rumpled or uneven andfree to shrink. This is assisted by placing the toweling under pressureand tension of the depending loop and pulling thereon is dispensing orpulling the towelingv out or down and in use, and in being'wound ortaken up on the roller W and the roll S, as well as the frictionalengagement and sliding against the rearlower truss rod 44 and the plate56 whereby the toweling'will be kept smooth and somewhat stretchedout-to normal condition or length of toweling for use will belmaintained in a loop of constant length, instead 'of shortening bydrying in a crinkled, wrinkled, folded or uneven condition.

WhileA I have illustrated and described the preferred form ofconstruction' for carrying. my invention into effect, this is capable ofvariation and modification without departing from the spirit of the'invention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariation and modifications as come within the scope of theappendedclaims.
